# A Closer Look At Keppel Corporation Limited's (SGX:BN4) Uninspiring ROE

Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). We'll use ROE to examine Keppel Corporation Limited (SGX:BN4), by way of a worked example.

Keppel has a ROE of 6.1%, based on the last twelve months. One way to conceptualize this, is that for each SGD1 of shareholders' equity it has, the company made SGD0.06 in profit.

### How Do I Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit Ã· Shareholders' Equity

Or for Keppel:

6.1% = S\$646m Ã· S\$11b (Based on the trailing twelve months to September 2019.)

Most readers would understand what net profit is, but itâ€™s worth explaining the concept of shareholdersâ€™ equity. It is all earnings retained by the company, plus any capital paid in by shareholders. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.

### What Does Return On Equity Mean?

ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the profit over the last twelve months. The higher the ROE, the more profit the company is making. So, all else equal, investors should like a high ROE. Clearly, then, one can use ROE to compare different companies.

### Does Keppel Have A Good Return On Equity?

By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. If you look at the image below, you can see Keppel has a lower ROE than the average (7.9%) in the Industrials industry classification.

That certainly isn't ideal. We prefer it when the ROE of a company is above the industry average, but it's not the be-all and end-all if it is lower. Nonetheless, it could be useful to double-check if insiders have sold shares recently.

### Why You Should Consider Debt When Looking At ROE

Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

### Keppel's Debt And Its 6.1% ROE

While Keppel does have some debt, with debt to equity of just 0.94, we wouldn't say debt is excessive. I'm not impressed with its ROE, but the debt levels are not too high, indicating the business has decent prospects. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company's ability to take advantage of future opportunities.

### But It's Just One Metric

Return on equity is one way we can compare the business quality of different companies. In my book the highest quality companies have high return on equity, despite low debt. All else being equal, a higher ROE is better.

But when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
